环境
| ceph-1 | 192.168.1.120 | deploy，mon＊1，osd*3 |
| ceph-2 | 192.168.1.121 | deploy，mon＊1，osd*3 |
硬件环境
操作系统：Centos 7.3软件环境
Openstack：Ocata
Ceph：Jewel安装Ceph
1: 准备repo yum clean all rm -rf /etc/yum.repos.d/*.repo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo sed -i '/aliyuncs/d' /etc/yum.repos.d/CentOS-Base.repo sed -i '/aliyuncs/d' /etc/yum.repos.d/epel.repo sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repovi /etc/yum.repos.d/ceph.repo
[ceph] name=ceph baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/x86_64/ gpgcheck=0 [ceph-noarch] name=cephnoarch baseurl=http://mirrors.163.com/ceph/rpm-jewel/el7/noarch/ gpgcheck=0yum update -y
2: 操作系统配置
启用Ceph monitor OSD端口
禁用Selinux
setenforce 0安装ntp
yum install ntp ntpdate -y systemctl restart ntpdate.service systemctl restart ntpd.service systemctl enable ntpd.service ntpdate.service无密码访问配置
配置deploy节点和其他ceph节点之间的无密码访问 sudo su - ssh-keygen ssh-copy-id ceph-1 ssh-copy-id ceph-23: 部署Ceph集群
安装ceph-deploy
yum install ceph-deploy -y 用Ceph-deploy创建Ceph集群 mkdir /etc/ceph cd /etc/ceph ceph-deploy new ceph-1安装ceph二进制软件包
ceph-deploy install --no-adjust-repos ceph-1修改ceph 配置文件
[global] fsid = 7bac6963-0e1d-4cea-9e2e-f02bbae96ba7 mon_initial_members = ceph-1 mon_host = 192.168.1.101 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx public network = 192.168.1.0/24在ceph-node1上创建第一个ceph monitor
ceph-deploy mon create-initial在ceph-1上创建OSD
ceph-deploy disk list ceph-1(列出disk） ceph-deploy disk zap ceph-1:sdb ceph-n1:sdc ceph-1:sdd ceph-deploy osd create ceph-1:sdb ceph-node1:sdc ceph-1:sdd总结
通过上面的步骤，一个all in one的ceph就成功部署了。检查ceph的状态。
ceph -s
